For people who are knowledgeable about heads up hold'em.

I'm wondering how much of a disadvantage you think it would be to open fold your big blind preflop every single hand. Do you think it would be crippling, and it would turn even a big favorite into an underdog, or not? You can answer seperately for limit and no limit if you believe there to be a significant distinction.

The idea occurred to me when I was thinking about this: what if you were playing heads up against someone you suspected to be rigging the deck each time he dealt? If you just tossed your hand without looking and surrendered your big blind each hand, would you still have a shot against a competent opponent?
